Briefly, this error occurs when Elasticsearch is unable to delete a specific role, possibly due to insufficient permissions or the role being currently in use. To resolve this issue, you can try the following: 1) Ensure that the user attempting to delete the role has the necessary permissions. 2) Check if the role is currently assigned to any user. If so, unassign it before deletion. 3) Verify that the role actually exists. If it doesn’t, the error might be due to a typo or incorrect role name.
